    I'm using nforce2-apic.patch and nforce2-disconnect-quirk.patch that
    Andrew Morton have sent to me. I think they have been included in
    previous mm kernels but now are droped because they caused some
    temperature problems for some people with no nforce motherboards.

    If you want it, I can send it to you.

    By the way, is anyone involved in solving the IO-APIC thing in nforce
    motherboards? Anyone trying a different approach? Anyone contacting
    nvidia about this problem?

    I don't think this could be a reiserfs problem, because all the computer
    gets frezzed and locked, but perhaps someone at Namesys can realize why
    files gets deleted all over the hard disc.



    Thanks.
